What are normal vibration levels with the Silverline sensor unit on Trex 450?

aschobel · 06-15-2012, 10:12 AM

Did a bench test and the software shows Vibe act as 295 and Vibe Max as 380.

Sensor is mounted on the gyro shelf on a Trex 450 Pro V2.

Are these values within norms?

Also do not change the sub-trim on the throttle. The stock Align ESC would not initialize correctly, rapid beeps, with a a full power spool up right after (even in TH). Only had -3 on the throttle sub-trim, yikes.

On the bench without blades I get around 92!

Do bigger birds tend to have fewer vibrations?

When I touch the tail boom brace I feel a bit of vibration.

I'm new to the sport so I'm not sure if this is normal.

Hi,

mount the sensor inverted on the bottom plate from below. 1mm forward of aft landing skid and cable facing forward.

this helped me reduce the tail vibes.

came down from +300 to 100-150.

tape: Use stock if you have any left, otherwise use the hardest you can find.
i use on my silver the stock, but on the blue i also have used, what i call, "green outdoor gel type double face tape" - dont know the name.

with blue sensor on bottom an following tape

i get only 3-5 raised vib warning in the logs.

BUT this is too soft for the SILVER sensor...so use something harder and youll be happy

greetings
